Let the number of days = x
Margo practices her flute 1/4 hour each day.
Total number of hours =

Week = 7 days
So, the number of hours Margo practices her flute in 1 week =

Part B: Write and solve an equation to find how may minutes Margo practices her flute in 1 day.
Let the number of minutes = y
Total number of minutes =
Hour = 60 minutes
Substitute with y = 60
So, the number of minutes Margo practices her flute in 1 day =
minutes
The number of minutes she practices in 1 week = 15 * 7 = 105 minutes.
